Using HP PC Hardware Diagnostics (UEFI)
HP PC Hardware Diagnostics is a Unified Extensible Firmware Interface (UEFI) that allows you to run
diagnostic tests to determine whether the tablet hardware is functioning properly. The tool runs outside the
operating system so that it can isolate hardware failures from issues that are caused by the operating
system or other software components.

2. To power on the tablet, press the Power button, and then press the Volume down button.
3. Select System Diagnostics.

NOTE: If you need to stop a diagnostic test while it is running, press anywhere on the screen.
To start HP PC Hardware Diagnostics UEFI using a keyboard:
